Application tiled April l, 1895. Serial No. 543,987. (No model.)

.To all whom ma-yconcern:

Be it known that I, MICHAEL J. OWENS, a citizen of the United States of America, residing at Toledo, in the county of Lucas' and State of Ohio, have invented new and useful Improvements in Machines for Blowing Glass, of which the following is a specification.

This invention relates to a partially-automatic machine for blowing glass into pastemolds, the object being to providea machine which is susceptible of practical use for the rapid production of large quantities of glass vessels or objects of a given shape.

The machine of this invention embodies a means for supporting the blow-pipe with its one end in communication with the air-supplying device and'its other in operative proximity to or within the mold; certain means for automatically admitting air through the blow-pipe; a sectional mold, which is adapted to be closed about or adjacent the gathering end of the blowpipe and to be also automatically opened, whereby the pastecovered inner surface thereof may be subjected to a sprinkling action; means for automatically eifectin g the closing and afterward the opening of the mold-sections and for imparting to them while they are closed rotary motions, and means for automatically causingasprinkling of the paste-lined mold-sections whilel opened. The automatic operations are instituted by and in consequence of the placing of the blow-pipe which'has the gathering of glass thereon in the machine in its position of support and for the reception of air communication therethrough.

The invention consists in certain constructions of devices and in the combination for co-operative action of various devices, all substan tially as will hereinafter fully appear and be set forth in the claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a side elevation of the present improved machine, the blow-pipe being shown in place and the mold closed. Fig. l is a perspective view of the mechanism which operates the yoke which closes the mold and permits it to open. Fig. 2 is a front elevation of the machine. Fig. 3 is a horizontal section as taken on the line 3 3, Fig. 2, showdated October 22, 1E 95.

ing part of the machineviz., the sectional mold and the operating-yoke therefor. Fig.

4 is a front elevation of the part shown in Fig. 3, the yoke being seen in vertical section. Fig. 'is a' plan view as seen below the plane indicated on the line 5 5, Fig. 1. Fig. 6 is a vertical sectional view of parts as taken ou the lin'e' 6, Fig. 5. Fig. 7 is a central vertical section through the clutch mechanism which effects the starting and automatic stoppingof the machine. Fig. 8 is a cross-sec tional'view of the intermittently-operating shaft on which the clutch is mounted, together with a face view of the clutch. Fig. 9 is a similar view as taken on the same plane of cross-section as Fig. 8, but looking in the opposite direction, whereby the face of the constantly-rotating gear-wheel is seen. Fig. 10 is a plan view of the parts seen in Fig. 7 below the plane indicated by l0 10.

Similar characters of reference indicate corresponding parts in all of the views.

A detailed description of the mechanism and parts thereof will be now given, to be followed by the description of the operation.'

The machine embodies the standard A of suitably massive and stable construction and having a wide base, and has near thebottom thereof bearings for the horizontal rotatable shaft B and also for the driving-shaft C. Above the shaft B are, at varying heights, the forwardly-extending shelf-like projections D, E, and F.

Thebracket D has vertical bearings for the shaftG, which at its upper end carries the base a, upon which the mold-sections b b are vpivotally supported, they having suitable ears,

which are pinned to lugs provided upon said base.

, which also has the pinion fthereon that The mold-supporting shaft Gr by the bevel-v 0fearscl has connection with the counter-shaft ICO closed positions, which positions are seen in Figs. l and 2. The yoke has the depending adjustable screw g, the lower end of which is in bearing against the vertically-movable hat' h, the roller h2, journaled at the lower end thereof, resting peripherally upon the camwheel J, which is fixed upon the aforesaid shaft B.`

The bracket E, as particularly seen by Figs. 5 and 6, has the recess t' within its forward edge, the width of which at its inner boundary is such as to permit the engagement thereat of the necked-down portion 2O of the blow-pipe K. The dogjis mounted upon the top of the bracket e, and is connected to swing thereon across and away from across saidrecess t', and also to have in addition to `its swingingr moveinentan endwise-sliding movement, all by-reason of the pin-and-slotconnection indicated at a", Fig. 5. The stop-pin 22 litnitsundue inward-swinging movement of this dog.r Under and alongside of the bracket E is a rock-shaft-L'having at its opposite ends the upwardly and the more or less nearly horizontally extending arms Z and Z2, the oneZ being in engagement with the aforesaid dogj to be lby the dog swung when the latter has imparted to it its endwise-sliding movement. to it the dexible con nection Z3, which is secured to the bar m, which is movable vertically in suitable gnideways therefor. This bar has appliedftliereto the spring m2, whereby itnorinally is forced to the limit of yits downward movement, which is inthe-path ofthe clutchdog o, carried by and within a suitable recess of the clutch-carrier o2, whichis afxed upon the aforesaid `shaft B. The springe3 exerts a tendency to move the dog o, when it may be permitted so to be moved, into clutch :engagement with the wheel M, which is loose and constantly rotating upon the shaft B by reason of its being geared to the driving-shaftl C. The lower extremity of the aforesaid bar m is beveled, as seen by the cross-sectionof this bar, which appears-in Fig. 10.

The reservoir N is supported beneath the bracket E and between it and the level of the sectional paste-mold and has the conduit g, leading forwardly from its front and terminating in the branched extremities,which are provided with the downturnedsprinklersqg, arranged and directed for sprinkling .the paste-lined surfaces of the mold-sections when the latter are permitted to be swung open. (See Fig. 4t particularly.) The conduit q has the valve, which is sulliciently indicated at s, and to the operating handle or Llever thereof is secured the cord which runs therefrom-npwardly around the sheave s3 to a connection with the aforesaid dogj.

'lhebracket F supports the hollow arm-Q, which has the two chambers or passages t and u therein, one leading from-thesource ofl airsupply and the other terminating inthe downwardly-directed opening u2, within which is the vertically-movable tube tts, having ati-its The other arm Z2 has -conne'cted Wheel M, which is loose on-the shaft B.

lower end the downwardly-flaring receivingsocket for the upper end of the blow-pipe K. The passages t and u are separated by the webwall t2, having the opening 3, which forms communication between said passages. The opening t3 is normally closed by the valve c, to-which is provided the spring fvg. The intermediately-pivoted lever tu has one end in bearing engagement against: the upper end of the aforesaid vertically-movable tube a3 and its other arm rests upon the top of the valvestem.

When the blowfpipe has its shouldered central portion 2O moved into the recess 1I at the forward edge ofthe shelf, which it engages fory its support, it exerts a cam-like action against the inclined `end of the dog, causing the-latter to moveendwise, which it is permittedvto dolby reason ofthe slot within which the pivot (seen-at zr)protrudes. This imparts against the resistance of the spring fm2 a swinging movement to the rock-shaft arm Z, a rocking movement to thetsaid shaft, a swinging .movement `to the rock-shaftarrn Zand an-endwis'efdrawing of the vertical trip-bar tta-which releases-the clutch-dog to the action of its spring owhereby the clutch is thrown intoengagement with the constantl T-rotating This clt'c'lrisof a well-known kind and is illustrated-in Figs-."7 toit), inclusive, and having made one revolutionm-the clutching-dog, by impingenient against the beveled'side-of the trip-har, (whioh,'fafter havingtbeen raised to permit the clutch to start, promptly snaps back by reason of the spring to its original position in the path of revolution of the clutchdog,) forces the dog inwardly within the recess `therefor and out ofthe clutch, whereby further rotary motion :is arrested until the nextoperation. Theabove-mentioned clutch, perse, constitutes nopart of thepresent in- Vention.

Preparatory to starting the machine the cam-wheel, which is outhe intermittently-rotating shaft C,.stands with th'e lowest part of the cam upward-and in-contact with the camroll on the vertically-movable bar h of the mold-yoke, which latter therefore is dropped to its lowest `position by gravity, the molds having automatically opened, all Aas seen in Figs. 3 and 4; but as the cam-begins its movement itelfects `the raising of the yoke and the maintenance thereof in its raised position until the cam has completed its circuit, whereupon the yoke'descends and the mold-sections open by reason of the gravity effect of the weighted wings thereof.

The mold-supporting shaft, deriving its rotary ,movement-concurrently with the elevation-of the mold-yoke throngh'theaforementioned gearing d clff, has its speed multiplied, so that Vthe mold has several rotations aroundthe stationary blow-pipe before being permitted to open. As the yoke is next permitted to descend at the time when the machine stops, whereby the mold-sections are spread open with their inner surfaces upward and whereupon the blow-pipe may be romoved, there will 4be concurrent with the removal of the blow-pipe and outward swinging of the dog j, through the cord-and-lever connection with the valve S in the conduit leading from the liquid-reservoir to the sprinklers, an opening of said valve, resulting in the sprinkling of the exposed paste-covered surfaces of the mold-sections.

Of course it is to be understood that when the blow-pipe is brought to its position in the flaring socket tv* by forcing the endwise movable tube ua upward, which it does as it seats itself, it swings the lever w to open the valve to the communication with the air-supplying conduit or reservoir, the opened communication continuing until the removal of theblowpipe.
